Colorado Ammonite Identification

Ammonite is a realistic Colorado fossil profile built around coiled marine shell with complex sutures from warm Cretaceous seas. In this state, success usually comes from learning Morrison outcrops, Green River beds, and uplifted marine limestones, then timing runoff, reservoir drawdown, surf cuts, or road work that exposes fresh fossil-bearing rock instead of hunting blindly.
